Reduced crude oil leaving a distillation unit with a flow rate of 3166.04 kL/d at 268 oC and is to be cooled to 243 oC by exchange with 62.8 kg/s pre-flashed crude oil coming from pre-flash unit at 206 oC. A pressure drop of 0.8 bar is permissible on both streams. Allowance should be made for fouling by including a fouling factor of 0.0003 (W/m2.oC)-1 on the reduced crude stream and 0.0002 (W/m2.oC)-1 on the pre-flashed crude stream. Design and optimize a suitable shell-and-tube heat exchanger that can satisfy the above- mentioned duty. It should be noted that any assumptions made in the calculations are to be explicitly stated and justifiable reasons to avoid penalty during assessment of individual report submissions. Hints: Fix a tentative geometry and perform all standard calculations. Verify the adequacy of your proposed design in terms of operating parameters; and Modify the proposed design to make them compatible with the required allowances of parameters. 2. Process Data Note that both pre-flashed crude and reduced crude are completely liquid over the range of temperatures and pressures experienced in the exchangers.
